Are 2006's 4th Generation????

[PGiannetto]

They changed the headlights & the grill. They also changed the dash. Pretty much the same changes that took place between 2nd & 3rd Generations.

Short answer is "NO"...



'03's made significant engine changes, as well as suspension, interior and sheetmetal - other substantial drivetrain changes soon followed. But there were FAR more upgrades done between '02 and '03 than between '05 and '06...

03 was a completely new truck from 02. Of course some driveline components carried over, but vehicle wise an entirely new design.

Which driveline components got carried over from 02 to 03 ?

The transmissions and transfer cases.



Not only did the engine get HPCR for '03 there were quite a few internal changes too, including a new block, bedplate, head design, fractured-cap rods, etc.

 

[Bob4x4]

47re and 48re are different. nv241 and nv 271 different? I don't see the carry over.

47RE's were used in the early 03's. I'm not sure about the T-Cases.

The changes made from 05-06 are much of the same changes they made from 1997-98.

 

[DMcAnulty]

If the '06 CTD's don't have the '03-'05 vibe, they ought to be designated as 4th generation.

Good point!

 

[klenger]

The NV5600 was carried over from 2nd gen to 3rd gen with no changes that I am aware of.

 

[NIsaacs]

The NV4500 5-spd was also a carryover in the 3rd gen. SO trucks untill "04. 5" when the 325/600 HO come out, certified in all 50 states.

Its what the industry like to call a refresh, then the full-on redeisgn will come in like 2009 - Product cycles are becoming really short to keep customers coming back, But then even 4 year old cars look dated...

 

[Scrappy]

after '03 there were no more SO's and 47RE's

Actually the SO's lived in California and several eastern states cuz, HO's were not allowed. Not until 04. 5 did they go away.

Gen III.5

I vote for Gen III. 5

 

[Tomeygun]

I vote for Gen III. 5

Then when the 07's come out and they have the 68RFE - maybe a GEN III. 75?



Opps, I've said to much... :-laf
